For example, there are over 100 WooCommerce extensions that connect via APIs (application programming interfaces) to different payment providers to process transactions. More seriously, server-side scripting is used in ecommerce. Server-side programming is useful for delivering dynamic content (typically from a database) to users, such as a welcome message (“Hi, Claire!”) when a user logs in. This means that it runs on the web server as opposed to a client machine. What Are the Differences Between PHP vs JavaScript? JavaScript teacher Chris Ferdinandi laments the lack of good JavaScript documentation, saying that it was one of the reasons it took him so long to master the language.Īt this point, you might be wondering, “What is the difference between PHP vs JavaScript?” Actually, there are several. You can check out the documentation for each language here: It’s been written for experienced developers rather than beginners. The less good news for newcomers to PHP or JavaScript is that the official documentation for both languages is not very user-friendly. PHP Developer Salaries, JavaScript Developer Salaries, Documentation In the USA, they make an average of around $80,000 a year. Market DemandĪnother thing that PHP and JavaScript have in common is that developers for both languages are in high demand.ĭevelopers using JavaScript and PHP are also well compensated. Hence a sorcerer’s apprentice object will not be able to cast spells as effectively as a seasoned wizard object. When a method is run on an object, the outcome may be dependent on the object’s properties. You can also define methods which are actions that the objects take, or have performed on them. When this code is added to an HTML file, the output in the browser should be the following: # Output the object properties in the browser $yensid = new Sorcerer("Yen Sid", "Human", 18) Here is a PHP code example of a class and object definition: You can use object methods to retrieve information about the object. alignment (lawful, chaotic, good, evil).abilities (Strength, Intelligence, Wisdom, Dexterity, Constitution, and Charisma).So, a character’s properties may include: Objects can have any number of properties that you care to define. Each character belongs to a character class, such as a Barbarian, Rogue, or Wizard. The game Dungeons and Dragons (D&D) provides a good analogy.Ī player character corresponds to an object. They came into the language in 2015, with ES6’s introduction.Ī class is a generic grouping of objects.Īn object is an entity with properties (characteristics) and methods (behaviors). JavaScript did not use objects or classes until much later. The ability to create objects and classes came in with PHP 5, in 2004. Object orientation was added to them as the languages evolved. Neither PHP nor JavaScript were originally object-oriented. A new, improved version of gettype, get_debug_type, is part of the PHP 8 release. PHP has the gettype function to return a variable’s type. JavaScript has the typeof function to do this. x = 3.14195 īecause types aren’t defined explicitly in PHP or JavaScript, you need functions to tell you what data type you are working with. This is opposed to a strongly typed language like Java, where you must say what type of variable you are using when you declare it: int x = 5 īoth PHP and JavaScript are dynamically typed: in other words, you can change the type easily by redefining it in your code: $x = 5 In both languages, these variables will be recognized as strings (sets of characters). Or in JavaScript: var x = 'Coding is fun' So, you can write the following in PHP: $x = 'Hello world' This means that when you create a variable in either language, you do not need to assign its data type: it is assumed. Typing of VariablesĪnother commonality is that PHP and JavaScript are weakly typed. This is why compiled languages tend to be faster than interpreted languages. If you didn’t know the Navajo language you’d need an interpreter to help you, and the translation would take more time. Think of it this way: imagine you want to translate a web page from your native language into Navajo. That means they are translated into machine code via a third party rather than directly. Scripting languages tend to be interpreted rather than compiled. This is as opposed to ‘pure’ programming languages such as Java or C++. PHP and JavaScript are both scripting languages.
